Mini projects/examples that can be learned from to make larger projects

For the mini projects, think of them as bricks to build a house. We have very few bricks right now!

Not sure if anyone else noticed the suggestion of "Arduino cloud compile (cross-compile your C/C++ code in the cloud & have your binary pushed to the Arduino automatically, wirelessly, remotely)" that one for me is a no-brainer.

It would allow current users (personal, professional & educational) of the popular Arduino* boards to port their existing projects over to a more powerful/flexible device.
